INTERNAL-COMBUSTION ENGINE.

Specification of Letters Patent.

Patented Dec. 19, 1916.

Application filed April 18, 1913. Serial No. 761,941.

To all whom it may concern Be it known that I, JULIAN S. Brown, of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Internal-Combustion Engine, of which the following is a specification.

This invention relates to internal combustion engines and particularly to the arrangement of the inlet and exhaust ports and valves;and it consists in the combinations and constructions hereinafter set forth and claimed.)

In describing this invention reference is had to the accompanying drawings in which like characters designate corresponding parts-in all the views.

Figure l is a vertical sectional view of one form of my internal combustion engine. Fig. 2 is a View similar to Fig. l, of a slightly modified form thereof. Fig. 3 is a transverse sectional view of a plan of line A-A, Fig. 1.

This internal combustion engine comprises, generally, a cylinder formed with a passageopening into the cylinder chamber, inlet and exhaust ports opening into the passage, one of the ports, as the exhaust port, being arranged between the other-port and the cylinder chamber, whereby the charge entering through the inlet port passes 7 over the heated exhaust valve and cools the same.

The invention further comprises the arrangement of the valves whereby they are actuated by a single cam shaft.

1 designates the cylinder having a pas= sage 2 opening into a chamber?) thereof, and

inlet and exhaust ports 4 and5 opening into the passage 2,, these ports being connected.

respectively to a carbureter 6 and an eX- haust pipe 8 and 9 are valves for controlling the flow through the inlet and exhaust ports 4 and 5.

. 10 is the piston movable in the cylinder 11 by the pitman 12 in the usual manner.

The walls of the cylinder chamber 3, the passage 2 and the ports 4 and 5 are formed integral and are surrounded by an integral water jacket 13. The passage 2 extends laterally at the head of the cylinder, and the ports 4 and 5 are arranged side by side ina line extending in a direction transversely of the engine, the exhaust port 5 being located between the inlet port 4 and the cylinder chamber 3 so that the'incoming cool charge entering through the port 4 passesover the head of the exhaust valve 9 and cools the crank shaft by suitable gearing 19, Fig. 3,

and extending from end to end of the englne.

g The heads of the valves 8, 9 are held against their seats by springs 20 and 21 encircling the stems of the valves and bearing at their lower ends against shoulders 22 on said stems and at their upper ends pressing on collars 23 which are fixed relatively to the contiguous portion of the water jacket 13. Usually the stems 14, 15 of the valves are inclined relatively to each other and converge downwardly so that their lower ends, which are provided with suitable anti-fric-. tion means, can coact directly ,with the cams on the cam shaft. If desired, however, the

arms, 24, 25 which coact respectivel with the stems 14, 15 and the cams l6, 1

The valves 8, 9 are removable through passages opening in the upper side of the passage 2 opposite the ports 4 and 5, these passages being closed respectively by plugs 26,- 27, a spark plug 28 being carried by the plug 27. The upper portion of the engine is covered by;a cap 29.-

This engine construction is particularly advantageous in that the exhaust valve is arranged 'to be cooled by the incoming charge.

Although I have shown but a single cylinder, it will be understood that this arrangement isparticularly desirable in multi-cylinder engines.

What Lclaim is: I

1. An internal combustion engine comprising a cylinder having a passage opening into, the piston chamber thereof and ex-' tending laterallytherefrom, and inlet and exhaust. ports opening into the passage and arranged side by side in a line extending laterally of the engine/whereby the gas,

valve, inlet and exhaust valves for controla ling said ports, and a single cam shaft having means arranged to operate both valves,

passing by one valve, passes over the othershaft and extending substantially from end to end of the engine, said cam shaft extending under the valves, substantially as and for the purpose specified.

2. An internal combustion engine comprising. a cylinder formed with a laterally extending passage opening into the piston chamber, inlet and exhaust ports opening into the passage on the under side thereof, the ports being arranged side by side in a direction laterally relatively to the cylinder, and the exhaust port and valve being arranged between the inlet port and valve and the piston chamber whereby the cool incoming charge passes over the exhaust valve, the valves'being formed with vertically extending stems, and a single cam shaft offset from the crank shaft and located at one side of the: cylinder and under the laterally ex cylinder formed with a laterally extending laterally relativel to the en inc and one port and valve being arrange between the other port and valve and the cylinder chamber, said valves being formed with vertically extending stems, and a single cam shaft arranged on one side of the engine and having means for actuating said stems, the stem of one valve being inclined relatively to the stem of the other valve whereby the stems converge toward their lower ends near which is located the cam shaft, substantially as and for the purpose described.

In testimony whereof, I have hereunto signed my name in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, and State of New York, this 29th day 'of March, 1913.
